Syntax

toPrecision(digits, roundingMode?, radix?)

Parameters

• digits

• roundingMode optional

  A rounding mode as in BigFloatEnv. Defaults to BigFloatEnv.RNDNA (Round to nearest, with ties away from zero rounding mode).

• radix optional

  The radix of the result between 2 and 36. Defaults to 10.

Return value
